Common Mistakes to Avoid When Replacing a Heating Furnace in Liberty Lake, WA

Replacing a furnace is a major investment for any homeowner, and making the wrong decisions can lead to wasted money, inefficient heating, or ongoing maintenance issues. Understanding the common mistakes to avoid can help ensure your new furnace provides reliable comfort for years to come. With this in mind, we at AirForce One Heating & Cooling would like to share common mistakes to help you avoid them during the furnace replacement process.

Choosing the Wrong Furnace Size

One of the most frequent errors homeowners make is selecting a furnace that is too large or too small for their home. A furnace that is too small will struggle to heat your space efficiently, leading to higher energy bills and uneven warmth. Conversely, an oversized furnace will cycle on and off too frequently, increasing wear and tear and reducing efficiency. Always rely on a professional HVAC technician to perform a proper load calculation before purchasing a new system. This calculation takes into account your home’s square footage, insulation, number of windows, and climate, ensuring you get the right size for optimal performance.

Ignoring Energy Efficiency Ratings

Energy efficiency is a crucial factor when replacing a furnace. Furnaces with higher Annual Fuel Utilization Efficiency (AFUE) ratings use less energy to produce the same amount of heat, saving you money in the long run. Failing to consider efficiency can result in higher utility bills and a less environmentally friendly home. Look for ENERGY STAR® certified models, which meet strict energy efficiency guidelines. While high-efficiency furnaces may have a higher upfront cost, they often pay for themselves over time through lower monthly energy bills.

Overlooking Ductwork Issues

Even the best furnace can underperform if your ductwork is old, leaky, or poorly designed. Ignoring ductwork inspection and maintenance is a common mistake during furnace replacement. Leaky ducts can allow warm air to escape into attics or crawl spaces, reducing system efficiency by up to 30%. Properly sealed and insulated ducts ensure consistent airflow and improve overall system efficiency. Ask your HVAC professional to assess your duct system and make any necessary repairs during the replacement process.

Skipping Regular Maintenance After Installation

Some homeowners assume a new furnace doesn’t require maintenance, but regular servicing is essential to maintain efficiency and prevent breakdowns. Ignoring routine maintenance, like filter changes and annual inspections, can shorten your furnace’s lifespan and lead to costly repairs. A professional HVAC technician can identify small issues, such as worn belts or minor leaks, before they become major problems. Setting up a maintenance schedule helps your system run safely, efficiently, and reliably throughout the heating season.

DIY Installation

While it may be tempting to save money by installing a furnace yourself, DIY installation can lead to safety hazards and void manufacturer warranties. Gas and electric furnaces involve complex connections that require professional expertise. Improper installation can create dangerous situations, including gas leaks, carbon monoxide exposure, or electrical hazards. Hiring a licensed HVAC technician ensures the installation is safe, code-compliant, and backed by warranties.

Not Considering Long-Term Costs

Another common mistake is focusing solely on the upfront cost of a furnace. While it’s natural to want to save money, choosing the cheapest option can lead to higher operating costs and more frequent repairs. Consider the long-term costs, including energy consumption, maintenance, and potential repairs. Investing in a quality furnace from a reputable brand often leads to better performance and peace of mind for years to come.
